Using Wireless Xbox Controllers

I Have the coin issue worked out and I have the Left Analog working like the DPad using the config entries below which seems to work for most lr-lmame4all games

# Change Hotkey so Select button works for coins
input_enable_hotkey_btn = 4

# Left Analog Sticks work same as DPad
input_player1_analog_dpad_mode = "1"
input_player2_analog_dpad_mode = "1"

The issue I am having is trying to get right analog stick working in games like Robotron… currently the directional fire works using the Xbox buttons… I would like to get the right analog stick performing the directional fire instead.

I can get into the RetroArch Input config but not sure which entries need to change and to what?

Any assistance or direction is appreciated!

Thanks!
